Talkback: Powdery mildew

Apparently mildew has been a prolific problem this year according to Mail Order Trees from whom I purchased a 2 year old Amelanchier canadenisis which quickly developed the disease. Have pruned heavily and will spray with fungicide.

  • I have powdery mildew on an red acer tree (I think it's a Crimson King Maple) which is over 25 years old. It had been heavily pruned in recent years to allow some more light in the garden. The mildew has also affected some other plants in the garden, ie my trailing begonias, this year. Should I take the tree out altogether?

    Hi

    I have it on my pulmonarias and lupins in the drier, full sun borders, elsewhere they are fine.  Honeysuckle is OK.  Teh only way to avoid is keep well watered in dry weather- water on an evening or early morning to prevent evaporation and use a mulch on those areas.

    The honeysuckle will be fine -With the honeysuckle and pulmonaris once it has flowered- prune, which will get rid of the mildew and will give you better flowers next year or a second flush later in the year.

    Just reminded me to go and shear my "frosted" pulmonarias and replant some in a shadier moister border!

    Lorraine, is it in a container?  If so how big?

    What sort of compost?

    How often are you watering it and how much?
